This is what I noticed, comparing the two systems with BrickOS One thing that I noticed was at the lower voltages the needle on my multimeter wavered around a little and it tended to steady at the higher power levels All of the readings were taken (...)

Ok, you can (perhaps--I haven't been able to test it yet) ignore my previous post. I was trying to build the cross compiler using GCC 3.3, and nothing I tried would work. When I switched to 3.2.3, the errors disappeared. So I'm making the temporary (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)

Has anyone had any luck creating a cross complier for the Mac? I've downloaded Michael Zapp's, but he said it wasn't working for C++. I've been trying to compile my own, but I keep getting errors. Any suggestions or pointers would be greatly (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)

(...) Actually there are four, sort of, as for 0 there are float (contacts separated, infinite resistance) and brake (contacts shorted, zero resistance). The standard firmware switches rapidly between on and float (each cycle takes 8ms), which (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)

(...) The eight different power level pulsing is called "PWM", translation=Pulse width modulation. PWM is the way a digital chip cheats/mimics true analog without a D/A convertor. Since the only output of a digital chip is on or off, there is no (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
